Comparing Two Medical Treatments for Early Pregnancy Failure.

Summary

This study aims to compare whether a combination of two drugs (Mifepristone and misoprostol) are superior compared to using only one of these drugs (Misoprostol) as medical treatment for a miscarriage. Women in whom early pregnancy failure, 6-14 weeks postmenstrual, is ultrasonographically confirmed qualify for this study. It is expected that the combination of Mifepristone and Misoprostol is more effective in reaching complete evacuation, and therefore can prevent more invasive treatment such as curettage.
